Postgres recovery_prefetch feature linked to outages
Original: Postgres recovery_prefetch can cause outages
A detailed write-up argues that PostgreSQL's recovery_prefetch setting, intended to speed up crash recovery, can in practice cause serious problems and even full outages in production databases. The author walks through real-world failure scenarios and recommends administrators review whether the feature is enabled on their systems, prompting discussion among database engineers about safe defaults and upgrade behavior.
Why now: Database administrators are alarmed that a default Postgres setting could destabilize production systems, prompting them to check their own configurations.
